Another possibility might be to rename 'silentoldconfig'.
instead of explaining the background in the help message.

Your git-log 'internal interface' implies
renaming has no impact.

Commit fb16d8912db5268f29706010ecafff74b971c58d
renamed oldnoconfig to olddefconfig
to match the name to its behavior.

Then, I want to drop the 'oldnoconfig' alias:
https://patchwork.kernel.org/patch/10172375/


If we worry about the compatibility just in case,
we can keep 'silentoldconfig' as an alias as well.



It is difficult to suggest a clear name,
but 'syncconfig' is the one I came up with.

Please suggest if you have a better idea.


What do you think?
